The backhaul segment of the network is traditionally made up of the intermediate point-to-point links between the core (or backbone) network and the small subnetworks at the network edge, where the base stations are. Since 5G is aiming for multi-Gbps data rates for subscribers, all this data will need to be backhauled at much higher rates, too.
This article is dedicated to describing the main components of the 5G Core Network -- as defined by the 3GPP – including an overview of the architecture, a description of the key individual network functions, and an example of 5G interworking with LTE.
This article discusses the ideas and enhancements currently being developed for 3GPP Release-16, with a focus on selected Rel-16 work items and study items. These enhancements cover not only 5G-NR, but also LTE, which is being advanced in parallel.
This article describes an S-band, packaged Doherty PA MMIC for use in 5G base station transmitter applications. The design, simulation, assembly, and subsequent measurement of the power amplifier IC are described.
By building upon known phase-locked loop modeling methods, and an assessment of correlated vs. uncorrelated contributors, an approach to track distributed PLL contributions across frequency offsets is presented.
